Section 7: MAINTENANCE
Plumbing System Clean-Up
For your new system to operate properly, you may need to clean the entire plumbing system of the precipitated iron that has collected in it or iron “bleed”
(staining) will continue to be a problem. The plumbing system includes all water treatment equipment (such as water softeners), water heaters, toilets, and
dishwashers. Please refer to the appropriate owner’s manual for instructions.
General Maintenance
Depending on your water quality, it may be necessary to perform maintenance on your fi lter system in order to ensure continued performance. This is due to low
pH, high manganese and/or the sacrifi cial nature of the fi lter media. The severity of your pH or the amount of water used will determine how often the fi ltration
system will need to be serviced. pH Plus is a pH boosting material that replenishes the same material that was dissolved into your water to make iron and manga-
nese reduction possible. ph PLUS can be purchased through your Dealer/Installer or our Customer Service Department at 1-800-222-7880.
3M Purifi cation Inc. recommends that you test your treated water pH once a quarter. When iron is the only problem, a water pH needs to be 7.2 higher. When
Manganese and Iron are present, the treated water pH needs to 8.2 or higher. The levels can be checked every three (3) months on location with the use of an
inexpensive pH test kit that can be purchased locally or from 3M Purifi cation Inc. Our part number for this kit is “17N” . When the pH falls below the recommended
level and Iron or Manganese is bleeding through into the fi nished water, it is time to add the pH Plus component to the fi lter. The amount of material to add to a
fi lter is as follows.
Standard bed fi lters
1- 3 ½ pound container of pH Plus for each cubic foot of fi lter material
Manganese bed fi lters (Identifi ed by an “M” in the model number, i.e APIF100M)
2- 3 ½ pound containers of pH Plus for each cubic foot of fi lter material.

Step by step procedure to add pH Plus to your iron and manganese reduction system.
1)
Turn the inlet and outlet knobs of the bypass valve located on the back side of the control valve. See fi gure 3 in section 3 for proper orientation.
2) Manual initiate a backwash cycle to relieve water pressure from the inside of the fi lter.
3) Disconnect the drain line and set aside.
4) Remove the control valve from the media tank by rotating the valve head assembly to the left (counter-clockwise).
5) Set aside in a secure location for reuse.
6) Using the funnel and centering device supplied with the unit originally, install over the distributor tube and inside the opening of the tank to aid in adding the
pH Plus material.
7) Using a ½ diameter fl exible tubing siphon about 12” of water from the tank to allow for adding the pH Plus.
8) Pour the recommended amount of pH Plus into the fi lter media and add water back to fi lter to expel any air pockets in the tank.
9) Reinstall the control valve back on top of tank by attaching the valve head to the media tank by rotating the valve head assembly to the right (clockwise).
You may want to apply some silicone lubricant to the O-rings, distributor tube and the inside of the tank opening to facilitate for easier installation. Manually
stage control valve to the service position. Refer to Page 3-8, “HOW TO MANUALLY INITIATE IMMEDIATE REGENERATION”.
10) Connect both the bypass and the drain line to the control valve and hand tighten only the connection nuts.
11) Slowly open the inlet side of the bypass and pressurize the fi lter, check for leaks, correct if necessary.
12) Slowly open the outlet side of the bypass and pressurize the dwelling.
13) Manual stage the control to backwash and clean the fi lter media of any fi nes that would be present till clear. Allow the control to complete regeneration cycle
completely and return to service. Refer to page 3-8, “HOW TO MANUALLY INITIATE IMMEDIATE REGENERATION”.
